Type of oil to use in Pressure washing machine

[WFSTOTT]

Can you please tell me what type of oil you all use in your pressure washing machine engines?

SAE 30 weight nondetergent? 10W40?

what type do you use in your pumps?

I have a Landa 3500 PSI / 4GPM cold water machine. It has a Honda 13 HP motor and a GP pump.

Thanks.

I use 30w non detergent oil for the pump and in the engine I use Mobil 1 full synthetic oil

10-30 Mobil Fully Syn, as the Gunnman states.

30 weight non detergent is fine in most pumps,
it is best to always check pump manufacturers
lubrication specifications first just to be safe.

I use Mobil 1 in all my engines, even the lawnmower. Air cooled engines can use every advantage you can give them to keep their cool. The synthetic oil just does not break down....even after extended use, it's slick as the day you poured it in.

The problem with using synthetic oils in small enigne is that absent good filtration you cannot benefit from the longer life because oil still gets dirty. Lubricity and thermal resistance are good things but remember that oil also acts to suspend combustion products to prevent scoring of the cylinders that they cool and lubircate.

Leaving any oil in for longer than a year will dramatically increase the probability of damage from dirt not viscosity breakdown or excessive heat.

In the correct application synthetic oils are tremendous. In my TDI Jetta I change the filter every 6000 miles and the oil every 24000 miles. The benefit to me is much lower net cost of the oil change and my fuel economy benefits from the improved lubricity to the tune of 53 MPG at Interstate speeds.

Cheers.
